easyUI datagrid 合并行和列。

 $('#datagridtwo').datagrid({
            iconCls: 'icon-save',
            width: '99%',
            rownumbers: true,
            fitColumns: true,
            nowrap: false,
            height: 330,
            data: [{
                "conNo": "电力有限公司", "consName": "中电装备公司", "projectNo": "", "projectName": "", "type": "",
                "linkMan": "", "linkPhone": "", "projecttype": "", "projectendTime": ""
            },
            {
                "conNo": "综合能源公司", "consName":"综能服务集团", "projectNo": "", "projectName": "", "type": "",
                "linkMan": "", "linkPhone": "", "projecttype": "", "projectendTime": ""
            },
            {
                "conNo": "国家直流技术中心", "consName": "交流中心", "projectNo": "", "projectName": "", "type": "",
                "linkMan": "", "linkPhone": "", "projecttype": "", "projectendTime": ""
            },
            {
                "conNo": "直流建设分公司", "consName": "国网直流公司", "projectNo": "", "projectName": "", "type": "",
                "linkMan": "", "linkPhone": "", "projecttype": "", "projectendTime": ""
            },
            {
                "conNo": "交流建设分公司", "consName": "国网交流公司", "projectNo": "", "projectName": "", "type": "",
                "linkMan": "", "linkPhone": "", "projecttype": "", "projectendTime": ""
            },
            {
                "conNo": "英大公司", "consName": "英大长安", "projectNo": "", "projectName": "", "type": "",
                "linkMan": "", "linkPhone": "", "projecttype": "", "projectendTime": ""
            },
            {
                "conNo": "合计",  "projectNo": "", "projectName": "", "type": "",
                "linkMan": "", "linkPhone": "", "projecttype": "", "projectendTime": ""
            },
            ],
            fitColumns: true,
            columns: [[
                { field: 'conNo', title: '全称', align: 'center', width: 200 },
                { field: 'consName', title: '简称', align: 'center', width: 100 },
                { field: 'projectName', title: '采集电量（kW.h）', align: 'center', width: 120 },
                { field: 'projectName', title: '未采集分摊电量（kW.h）', align: 'center', width: 100 },
                { field: 'linkMan', title: '分摊系数（%）', align: 'center' },
                { field: 'linkPhone', title: '月分摊电量（kW.h）', align: 'center' },
                { field: 'projecttype', title: '总电量（kW.h）', align: 'center', width: 100, },
                { field: 'projectendTime', title: '总电费（元）', align: 'center', width: 80 },
            ]],
            onLoadSuccess:function(){
			var merges = [{
				index:6,
				colspan:2
			}];
			for(var i=0; i<merges.length; i++)
				$('#datagridtwo').datagrid('mergeCells',{
					index:merges[i].index,
					field:'conNo',
					colspan:merges[i].colspan
				});
		}
        });

重要解决跨行跨列的代码在onLoadSuccess 里 我这里用的是合并指定的单元格。
